Browse Source 
- app_settings: AI_IMAGE_BASE_URL → https://plus.nyxos.workers.dev/v1
- app_settings: AI_IMAGE_FALLBACK_BASE_URL/API_KEY → aiguoguo (резерв)
- config/index.js: загружает imageFallbackBaseUrl + imageFallbackApiKey
- covers.js: generateCoverViaImageGenerations пробует Nyxos, при 5xx/timeout
  автоматически переключается на aiguoguo
